+Add grok-cli as a provider. You can now use Grok models with Task Master by setting the `GROK_CLI_API_KEY` environment variable.
+
+## Setup Instructions
+
+1. **Get your Grok API key** from [console.x.ai](https://console.x.ai)
+2. **Set the environment variable**:
+   ```bash
+   export GROK_CLI_API_KEY="your-api-key-here"
+   ```
+3. **Configure Task Master to use Grok**:
+   ```bash
+   task-master models --set-main grok-beta
+   # or
+   task-master models --set-research grok-beta
+   # or
+   task-master models --set-fallback grok-beta
+   ```
+
+## Available Models
+- `grok-beta` - Latest Grok model
+- `grok-vision-beta` - Grok with vision capabilities
+
+The Grok CLI provider integrates with xAI's Grok models and can also use the local Grok CLI configuration file (`~/.grok/user-settings.json`) if available.
